Jesus christ why haven't I done this sooner...thanks for that
I'm still completely new to trading, and only mess around with a small amount (that's been designated for trading only, so no depositing if I do lose).

I won't laugh at all. You'd really be surprised how many people trade without metrics of their own. I have no idea how they can ever make a substantial profit without math.
